SWINGLETREE.

Specification of Letters Patent.

Application filed August 13, 1913. Serial No. 784,648.

This invention relates to new and useful improvements in swingle treesand has for its object the provision of a swingle tree which will beextensible.

Another object of my invention is the provision of a device of the abovecharacter which may be adjusted and is provided with a clevis to permitthe same to remain in its adjusted position.

With the above and other objects in view I now proceed to describe myinvention in the following specification and accompany ing drawings, inwhich, a

Figure 1 is a top plan view of my improved swingle tree showing the sameextended in the dotted position, Fig. 2 is a longitudinal horizontalsectional view of my improved swingle tree, and Fig. 3 is a transversesectional view talren on line 3-3 of Fig. 1.

Referring to the drawings by characters of reference 1 indicates atubular member forming a part of my improved swingle tree, having aclosed end, as shown at 2. This member 1 is provided at the endoppositethe closed end 2 with a suitable cut-away portion, as indicated,which forms a slot 3 as will be clearly seen upon referring to thedrawing. A second slot A is formed at right.

angles to the first mentioned slot and is adapted to permit the clevisto be adjusted with relation to the member 1.. A suitable plunger 5 isadapted to fit the interior of the tubular member.

Secured to the end of the plunger and the end of the tubular memberoppositeits open end I preferably provide the usual trace attachingmeanswhich is indicated by the numeral 6.; These trace hooks are of theordinary construction and comprise the loops having rings securedtherein. Intermediate the ends of the tubular member and Patented Oct.20, 1914.

surrounding the same I' preferably provide the band 7 which is formed ofa single piece of material and is extended rearwardly, as

shown at 8, to provide means by which the swingle tree is adapted to beattached to the remainder of the draft mechanism of a vehicle. Asuitable aperture 9 is provided in the upper side of the band 7 and isadapted to receive the bolt 10 by means of which the band is held inplaceon the swingle tree.

It will be clearly seen from the foregoing that when it is desired toextend my improved swingle tree the bolt 10 is loosened and the plungerextended to the desired,

point. The band 7 is then adjusted to the proper relation with theextended swingle tree and the bolt again tightened. It will be obviousthat the bolt 10 will hold the swingle tree in its adjusted position asthe inner end of the shank of the bolt extends through the slot in thetubular member and engages the plunger, thereby securely holding allparts and eliminating accidental movement of the device.

While in the foregomg I have shown and invention, I wish it to beunderstood that I may change the specific arrangement of parts withoutin any way departing from the spirit and scope of my invention. I

What I claim is j A device of the character described, comprising atubular body portion,a closure at one end of said tubular body portion,the op posite end of said tubular body portion being provided with aslot, said tubularbody portlon being provided with a centrally locatedlongitudinally extending slot, each of said slots communicating with theinterior of the body portion, a trace securing ring secured to theclosed end of the tubular body portion, an extension slid'able in thetubular body portion, atrace securing ringsedescribed the preferredembodiment of my ed to be held in the slotted end of the body curedtoone end of the extension and adaptslidable extension, and meanscarried by the ring to secure the same to a whiflietree. 10
